public class SetCharacterEncodingFilter implements Filter {
protected String encoding = null;
protected FilterConfig filterConfig = null;
protected boolean ignore = true;
// 设置申请对象的值为空，有利于内存资源的快速释放
public void destroy() {
this.encoding = null;
this.filterConfig = null;
}
// filter的主体操作
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
// 判断是否需要进行编码的设置
if (!ignore || request.getCharacterEncoding() == null) {
// 得到配置文件中的编码类型
String encoding = setEncoding(request);
if (encoding != null) {
request.setCharacterEncoding(encoding);
}
}
